In order to facilitate the positioning and installation of the motherboard interface panel and the graphics card interface panel, an interface panel mounting port 4 and a bracket mounting port 5 are provided at the lower rear side of the chassis body 1.

[0026] To facilitate heat dissipation for the hardware inside the chassis 1, air inlets and outlets are provided on the top and side of the chassis 1, respectively. A dust removal mechanism is installed on the opening side of the air inlet, and includes a dust collector housing 6, a dust filter element 7, and an intake fan 8, as shown in the attached diagram. Figure 3 As shown, three suction fans 8 are provided. The suction fans 8 are fixedly installed inside the air inlet opening by bolts. The dust collector holder 6 is used for connecting and installing the dust collector filter element 7. The dust collector holder 6 is detachably installed on the upper part of the main body 1 of the chassis. Specifically, see attached... Figure 4 As shown, in order to facilitate the installation and connection of the dust collector seat 6, mounting blocks 11 are evenly fixed at equal intervals on one side of the dust collector seat 6, and mounting slots are provided on the side of the main body 1 of the chassis. After installation, the mounting blocks 11 are aligned and engaged with the mounting slots. In order to lock and limit the dust collector seat 6 after installation, a fastening screw seat 12 is fixedly installed on the other side of the dust collector seat 6. After installation, the fastening screw seat 12 is fastened to the screw holes provided on the side of the main body 1 of the chassis by bolts. The structure is simple and easy to disassemble and assemble.

[0027] Dust collector filter element 7 is a dust filter sponge used to filter and remove dust from the intake air. Dust collector filter element 7 is installed inside the dust collector housing 6, as detailed in the attached document. Figure 3 As shown, to facilitate the connection and installation of the dust collector filter element 7, a filter element mounting groove is provided inside the dust collector housing 6. The dust collector filter element 7 is fitted and installed inside the filter element mounting groove. To install and seal the end opening of the dust collector housing 6, a housing end cover 9 is snapped and installed on the end opening side of the dust collector housing 6. The lower part of the dust collector housing 6 is connected to the air inlet. To facilitate air circulation, air inlet slots 10 are evenly provided on the upper part of the dust collector housing 6. The air inlet slots 10 are evenly opened through the upper part and side of the dust collector housing 6. When the suction fan 8 is working, the dust in the air is filtered and removed by the dust collector filter element 7 inside the dust collector housing 6, which can effectively prevent dust from entering the suction inlet side.

[0028] To reduce the ingress of external dust, a dustproof component is installed on the opening side of the air outlet. This dustproof component includes a dustproof frame 13 and a dustproof flap 14, as shown in the attached diagram. Figure 3 As shown, the air outlet is located on the lower side of the main body 1 of the chassis. The air outlet is recessed. To facilitate connection and installation with the main body 1 of the chassis, mounting posts 15 and springs 16 are provided on the side of the dustproof frame base 13. To facilitate the connection and installation of the dustproof frame base 13, a connecting hole is provided through the side wall of the air outlet. After installation, the end of the mounting post 15 is fitted into the inner side of the connecting hole. The spring 16 is fitted onto the upper part of the mounting post 15 on one side and abuts against the dustproof frame base 13. The dustproof frame base 13 is installed on the outer opening side of the air outlet by the cooperation of the mounting post 15 and the spring 16. The structure is simple and the installation is convenient.

[0029] The dustproof flap 14 is flipped and installed in the middle of the dustproof frame base 13, as shown in the attached figure. Figure 5 As shown, multiple dustproof flaps 14 are provided. Several dustproof flaps 14 are evenly rotated and installed in the middle of the dustproof frame 13 at equal intervals via a pivot. The pivot is supported on the upper part of the dustproof flaps 14, allowing the dustproof flaps 14 to move freely in the axial direction. When the heat dissipation is working, the dustproof flaps 14 are blown upward by the airflow inside and automatically flip up to open. After the heat dissipation is completed, the dustproof flaps 14 are automatically flipped down to close under the action of gravity. When the computer is not working, it can effectively prevent the entry of external dust and greatly improve the dustproof performance of the chassis. In order to support and limit the downward flipping of the dustproof flaps 14, a flap limiting post 17 is provided on the inner side of the middle part of the dustproof frame 13.

[0030] Working principle or structural principle: The intake fan 8 is pre-installed on the upper part of the chassis body 1. After the hardware installation inside the chassis is completed, the mounting buckle 11 on the side of the dust collector seat 6 is aligned with the mounting buckle groove on the upper part of the chassis body 1. Then, the dust collector seat 6 is installed on the upper part of the chassis body 1 by alignment and interlocking. The dust collector seat 6 is then locked and fixed by bolts and fastening screw seat 12. After completion, the dust filter element 7 is installed inside the dust collector seat 6 and the end cover 9 is fastened and installed on the end opening side of the dust collector seat 6. After completion, the mounting pin 15 on the end side of the dustproof frame seat 13 is aligned with the insertion hole on the side of the air outlet. Then, the mounting pin 15 is fully inserted into the insertion hole by side push and the spring 16 is compressed. After completion, the mounting pin 15 on the other side of the dustproof frame seat 13 is aligned and inserted into the insertion hole by pushing. Then, the dustproof frame seat 13 is released. Under the pushing force of the spring 16, the installation limit of the dustproof frame seat 13 is completed, and the chassis installation is completed.

[0031] During operation, the suction fan 8 operates, drawing in external air through the air inlet 10 at the top of the dust collection box 6. After being filtered by the dust filter element 7, the air enters the chassis body 1. The air is then blown out through the air outlet on the side of the chassis body 1 to remove heat. When the air is exhausted, the dustproof flap 14 is automatically flipped up and opened by the airflow inside, completing the air exhaust. After the heat dissipation work is completed, the dustproof flap 14 automatically flips down and closes under the force of gravity when the air is no longer pushed. This effectively prevents external dust from entering when the computer is not in use.

[0032] In summary, this computer chassis adopts a top-mounted air intake cooling structure, with a dust collection box 6 installed at the air intake. When the intake fan 8 is working, the dust filter 7 inside the dust collection box 6 filters and removes dust from the incoming air, effectively preventing dust from entering the intake side. Furthermore, a dustproof flap 14 is installed on the exhaust side of the chassis body 1. The dustproof flap 14 is supported and installed by a dustproof frame 13, which is fitted and snapped onto the exhaust side of the chassis body 1 using mounting pins 15. The structure is simple and easy to install. During cooling operation, the dustproof flap 14 automatically flips up and opens due to the internal airflow. After cooling is complete, the dustproof flap 14 automatically flips down and closes due to gravity. When the computer is not in use, this effectively prevents external dust from entering, greatly improving the chassis's dustproof performance.
